Yoshimoto Orton-Gillingham Approach (YOG-A) 40 hour Training 
This five-day O.G. training will focus on a data-driven, clinical, multisensory, phonetic, teacher guided Yoshimoto Orton Gillingham approach to teaching reading, writing and spelling in the whole classroom, small group, and one-to-one settings. Upon completing this course participants will have acquired the skills necessary to fully implement this 
science of reading, data-driven solution for teaching reading to all students.  Teachers implementing the Yoshimoto method with fidelity are demonstrating consistent and significant growth that is being replicated across the U.S. Perhaps more significant is that teachers love the course, the materials and the success they are seeing in their classrooms and interventions.

The course will cover the three levels of decoding and spelling: sound, syllable, and an introduction to the concept of morphology. With the latter, introductory morphology, the emphasis will be on increasing the vocabulary for all children - general and special education students. This results in students have all of the necessary skills required form student to read and comprehend - the goal for quaility reading instruction. Further, the system supports the outcomes within the Common Core.We also discuss Dyslexia, the brain and early and ongoing identification of these students.

All materials needed for implementation of the full program are included in the cost of the course. Further, there will be extensive additional materials provided including: multiple CDs with about 6,000 worksheets dealing with syllabication, sounds, rules and generalizations.

For whom is the O.G. approach appropriate?
The O.G. approach is appropriate for classrooms, small groups and teaching individuals; primary, elementary, intermediate, secondary, college, and adults. This class is designed specifically for kindergarten, primary, elementary & middle school classroom teachers, tutors, reading specialists, special ed teachers and home-school parents.

O.G. teaching sessions are action oriented with auditory, visual, and kinesthetic elements reinforcing each other; spelling is simultaneously taught with reading.

Structured, Sequential, Cumulative
Teaching proceeds from phonemic awareness, phonics, syllable types, syllable division rules, spelling, vocabulary, sentence structure, composition, and reading comprehension.

Data Driven, Flexible, Cognitive
O.G. is data-driven, diagnostic-prescriptive teaching at it's best. The teacher designs and implements lessons based on the data gathered from the individual student and/or the classroom group.  The instruction is targeted at the needs of the students and paced to insure the level of mastery that supports ongoing success for all students.  Further, the method includes targeted interventions for students who require more repetitions or intensity. The teacher always seeks to understand how an individual learns and devises appropriate teaching strategies using students' strengths while accommodating their weaknesses.


Meet Leslie Kesson, M.A.; Certified Master Trainer - Orton Gilllingham       International; CE/AOGOPe & A/AOGPE 

We are fortunate to have such a skilled trainer on the OGI team!  Leslie Kesson has  been teaching in the public school system for over 28  years. She attended the University of Northern Colorado and received  her Master’s Degree in Literac  y from the University of Colorado.

Her teaching career began as a classroom teacher, working in the  primary grades.For the past fourteen years she has been a literacy  teacher. This experience in combination with parenting two amazing,  challenging boys with ADHD is where she discovered her passion for  teaching students who do not fit the typical model of learning. Her    search for the right method to empower struggling students has brought  her to the path of embracing the Orton Gillingham (OG) approach.

 Leslie's first exposure to Orton Gillingham was by enrolling in the Orton Gillingham International Basic Training Course taught by Ron Yoshimoto Fellow of AGOPE. Impassionate about all that Orton Gillingham offers, Leslie continued on her OG path to becoming certified by the Academy of Orton-Gillingham Practitioners and Educators at the Classroom Educator Level. During this four year period to her certification, Leslie had been fervently working with her peers to implement a whole school model of OG instruction. This enthusiasm lead to sharing data, results and excitement about OGI in the public school setting. As word spread, parents and educators requested observations of OGI in action. A professional study team was then formed to continue to implement OGI with fidelity. Leslie and her peers discovered that by using the OGI approach and materials to link instruction from classrooms to lit lab and special ed, the data clearly supports what we know to be true—OGI works!

 Naturally, when asked to consider joining Ron Yoshimoto and Elenn Steinberg in moving OGI forward, Leslie’s response was, “When can I start?” Leslie’s ardent facilitation of  Yoshimoto OG has been an incredible asset to Orton Gillingham International and is in high demand by schools and districts for training and consulting.
